RAZGR CONSTRUCTION.

Application filed November 18, 1922. Serial No. 601,695.

To all whom z't may concern:

Be it known 'that I, FERNAN O. CoNILL, a citizen of the Republic of Cuba, and a resident of Marseille, France, have invented an Improvement in Razor Construction, of

which the following is a specification..-

This invention relates to razor construction and more particularly to safety razor construction. v

One' of the objects of this invention is to provide a simple and ractical safety razor construction that will) highly effective action when in use. Another object is to provide a durable and rugged, yet light, razor construction in which the cutting action of the blade due to a movement of translation or due. to the drawing thereof in a direction substantially transversely to the direction of the cutting edge of the blade is effectively combined with the cutting action resulting from a movement of the blade in a direction substantially coincident with that of its cutting edge without impairing the exibility of adjustment, convenience and precision ofmanipulation and ready accessibility of the parts for cleansing. Another object is to provide in a construct-ion of the above character a practical and reliable, as well as simple, arrangement for giving the blade a reciprocating movement in the direction of its cutting edge without detrimentally affecting the adjustment of the blade or its associated parts and without encumbering the construction and manipulation of the safety razor. Other objects will be in part obvious or in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts as exemplifled in the structure to be hereinafter set forth and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which are shown several of various possible ,embodiments of this invention and in which similar reference characters refer to similar parts throughout the several views,

Figure 5 is a bottom plan view of a guard plate;

Figure 6 is a cutting blade;

Figure 7 is a side elevation similar to that of Fig. 1 but showing a modified form of construction; and

Figure 8 is a vertical section taken on the line 8 8 of Fig. 7.

Referring now to the drawings and more particularly to Figs. 1 and 2, I have shown a main handle portion 10 preferably of elongated cylindrical form adapted to form a convenient gripping member for the hand. The handle member 1() is preferably hollow for purposes hereinafter more clearly de'- scribed, and vat its upper end has rigidly secured thereto a supporting member 11 in the plan view of a double-edged form of an elongated plate and associated.

with the handle member 10 so that its plane extends substantially transversely to the axis of the handle.

A supporting member 11 is provided with a longitudinally extending rectangularly shaped groove 12 (more clearly shown in Fig. l) adapted to forma guiding way for slidably supporting the guard plate 13; the under side of which is formed to fit wlthin the guiding way or groove 12. Thusthe' sol guiding surfaces provided by the guiding way 12 afford not only a rigid'supporting of the guard plate 13 with respect to the memberlll, but also insure an accurate guiding thereof during the relative movements that take place therebetween, as will'be more clearly hereinafter set forth.

In order to hold the guard plate 13 in sliding relation with the supporting member 11, the latter member is provided with longitudinally extending slots 14 and 15, more clearly shown in Fig. 4, and onel on each side of the handle member '10, through which eX- tend the detachable attaching members 16 and 17 respectively. -The members 16 and 17 are rigidlyy mounted upon guard plate 13 and are preferably ldetachable with respect thereto. For this latter purpose the members 16 and 17 are conveniently provided with threaded portions 16a and 17L respectively, threaded into the guard plate 13, and aS will be more clearly seen from Fig. 2 the attaching members 16 and 17 are provided with enlarged shoulder portions 16h and 17b respectively adapted to lit preferably snugly within the slots `14 and 15 respectively and slidable therein. The shoulder portions' 16D and 17 b may thus conveniently coact with the longitudinally extending slots 14 and 15 respectively' to assist in guiding the guard plate 13 throughout its movements with respect to the supporting member 11. The outer portions of the attaching members 16 and 17, as indicated at 16c and 17c respectively, are preferably of still greater diameter so as to overlap the underside of the supporting member 11 and thus securely hold the guard plate in its i Fig.A 6) is adapted tobe mounted upon slidable relation to the supporting member 11. Moreover, it will be seen that upon re moval of the attachin members 16 and 17v by unscrewing them om the ard plate 13, the latter with its associate parts may be readily removed.

Referring now to Fig. 5, it will be seen that the guard plate 13 is provided at its opposite side edges with a series of spaced,

integrally formed members, generally indi-1 cated at 18, with which ythe cutting blade is vadapted to coact. Referring now to Fig. 1, it will be seen that the upper face of the guard plate 13 is substantially plane-faced,

as at 19, throughout a substantial extent laterally so as to provide the projecting bladesupporting edges 13a and 13h respectively, it being noted that the spaced members 18 are inclined inwardly in a direction toward the supporting member 11. A blade member 20, preferably of thin steel and somewhat flexible and provided also with two' op ositely 'disposed cutting edges 20a, 2()b (gee the plane-faced 'side of the guard plate 13 so that the cutting edges 20a and 2Ob substantially overlap the supporting edges 13a and 13", respectively. The cutting blade 20 is preferably adjustably secured with respect tothe guard plate 13.

Referring now to` Fig. 2, it will be seen that the guard plate 13 is provided with a substantially vcentrally positioned and upwardly extending threaded stud 21, the stud 21 passing through al centrally positioned opening 20c in the blade 20 (see Fig. 6). After the blade 20 has th-us been positioned upon the plane-faced side of the plate 13 with the stud "21 extending through the opening 201, a blade-holding plate 22 is.

thereupon placed over the blade 2O in order to securely positionv the blade 20 with respect s to the guard plate 13. Forthis purpose the blade-clamping plate 22 is provided with two inwardly directed studs 23 and 24 preferably integrallyhformed therewith and adapted to pass through suitably spaced openings 23a and 24a in the blade 20. rIhe studs 23 and 24, moreover, are adapted to enter suitably formed and aligned recesses 23b and 24h, respectively, in the guard plate 13, thus aligning the clamping plate 22, as Well as the blade 20, with respect to the guard plate 13. A thumb nut 25 is rotataibly mounted as by means of the sho-ulder 26 within the central portion o-f the clamping plate 22 and is adapted to be placed in threaded engagement with the threaded stud 21 in order to adjust the clamping plate '22 toward or away from the guard plate 13.

As shown in Fig. 3, the guard plate 22 is curved transversely-to its longitudinal axis, and its opposite longitudinal edges, referring now to Fig. 1, are adapted to engage the outer edge portions 20a and 20b of the blade 20 which overlap the blade-supporting edges 132L and 13b respectively of the movable guard member 13./ The curved clamping plate 22 when moved toward the guard plate 13 by means ofthe thumb-nut 25 will cause the blade 20 to be bent muchin the manner as shown in Fig. 1, thus bending the cutting edges 20a and 20b toward the comb-shaped projections 18 of the guard plate 13. In this manner the cutting edges of the blade may be spaced from the comb-shaped portions 18 of the guard plate 13 to as great an extent as desired, in order thus to adjust the cutting action of the blade. n

Turning now to Fig. 2 of t-he drawings, the handle member 10 isbored out to a uniform diameter, as at 10a, throughout its extent to provide a suitable bearing surface for supporting a rotatable operating shaft 27. The shaft 27 is preferably of smaller diameter than the bore of the handle 10 but is enlarged at its respective ends, as at 27a and 27b to be rotatably supported in the bearing surface 10a. At its upper end the shaft is provided with a crank disk 28a of larger diameter than Athe bore 10a of the handle 10 and seated within a suitable recess 28b in the supporting member 11. In the crank disk 28a is a crank pin'28 eccentrically positioned with respect to the axis of the shaft 27 and projecting upwardly beyond the supporting and guiding member 11. The crank pin 28 is received within a transversely extending slot 29 substantially centrally positioned in the guard plate -13 (see Fig. so that upon rotation of the shaft 27 the crank pin 28 will transmit to the guard plate 13 and its associated parts a reciprocating movement, thus carrying both the guard plate 13 with associated blade 20 back and forth in a direction substantially coincident with the direction of the cutting edge or edges of the blade 20.

The lower end bearing portion 27"* of the shaft 2O is suitably formed at its lower end as at 27 c for detachable engagement with the end.d of a flexible shaft (not shown in the drawings) driven from any suitable source of motive power and at a suitable rate of speed. Thus the lower end of the handle 10 is hollowed out as at 10d for the reception of the endv of the flexible shaft and its sheath.

It will thus be seen that by means of the handle 10 the cutting edge (either 20a or 20h) of the blade 20 maybe given a movement of translation in aV direction substantially transversely to that of the cutting edge of the blade and that during such movement the blade itself, together with the guard platev '13, is given a vreciprocating movement in a direction substantially coincident with that of the cutting edge that is operated. It will moveover, be seen that the blade may be readily adjusted for the desired cutting action with respect to the comb-like edge portions 18 of the guard plate 13 without disturbing or detrimentally affecting the reciprocating movement thereof and the mechanism for bringing such movement about.

As will be seen in Fig. 2, the parts nmay be readily taken apart for cleansing purposes and that the operating shaft 27 may likewise be readily removed, it being held in place by the disc 28aL on the inside of the member 11 and, in effect, locked in position by the guard plate 13 itself, with which it is in operative engagement.

In Figs. 7 and 8 I have illustrated a modified form of apparatus in which'certain of the features hereinabove described are attained in a somewhat more simplified mechanical arrangement. It willbe seen, referring now to Fig. 8, that the handle 10 is bored out as at 10e throughout substantially its ent-ire extent, this bore being of uniform diameter throughout. The operating shaft 27 is provided with a lower eI1- larged bearing portion 27a and an upper engage the supporting member 11 but also tolarged bearing port-ion 27b of the same diameter and is held against axial movement in one direction by means of the removable screw stud 30 which is threaded into the handle 10 and against which the enlarged bearing portion h of the shaft 27 abuts. At its upper end the shaft 27 is provided with the crank pin 28 for engagement with the guard plate 13 to actuate the same in substantially the same manner as hereinbefore described, the guard plate 13 acting in effect also to `lock the shaft 27 against axial movement in an upward direction as viewed in Fig. 8.

The supporting member 11, however, is grooved longitudinally to provide a dovetailed way, generally indicated at 31, and the guard plate 13 is formed at its under side with a coacting portion 32 likewisev dovetailed, thus not only to slidjably enbe securely held in engagement therewith. The mounting of the blade 20 and its adoperating shaft 27\may be inserted in the bored-out portion 10e of the handle 10 to place the crank pin 28 in engagement with the slot 29 in the guard plate 13. The locking screw 30 is then driven home thus not only locking the shaft 27 against displace4 ment, but also, in so doing and acting through the shaft 27 and the crank pin 28, preventing the guard plate 13 from coming out of operative relation with the supporting and guiding member 11.

It will thus be seen that there has been provided in this invention a simple and practical razor construction in which the several objects hereinabove set forth are attained and in which many advantages are successfully achieved. It will be seen that the apparatus is of simple and rugged construction, is of convenient adjustment, and may be readily taken apart for cleansing purposes, being thus conducive to a high degree of sanitation. Moreover, it will be seen that the normal cutting action of the blade'due to the movement of translation manually imparted to it is effectively supplemented and combined with the cutting action due to the reciprocating movement in a direction substantially coincident with the direction of the cutting edge, and that such combined action is attained without interference with the simple mounting and ready and convenient adjustment of the blade for most eliicient use. Moreover, the construction is exceedingly light and is not impaired by complicated and cumbersome operating mechanisms, thus facilitating great convenience as well asprecision of manipulation, when in use.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that lll] all matter hereinbefore set forth or shown tudinally extending guiding ways, a guard plate slidable lengthwise with respect to said supporting Imember and, adapted to be guided by said guiding ways, means for detacliably holdingl said guard plate in assembled relation with respect to said guiding. ways, a cutting blade associated with said guard plate and having its cutting edge extending lengthwise thereof for coaction therewith, a rotatable shaft mounted within said hollow handle member and having a detachable connection with said guard plate for producing a reciprocatory movement of said guard plate with associated blade lengthwise of said guiding ways, said guard plate preventing axial movement of said shaft in one direction, and means releasably holding said shaft against axial movement in the other direction.
